Abstract

Cette invention concerne un appareil et un procédé de commande de la tension appliquée à un dispositif de précipitation électrostatique (66). Cet appareil comprend un mécanisme de tension à courant continu pulsé conçu pour recevoir de l'énergie provenant d'une source de tension à courant alternatif monophasé ainsi qu'un condensateur (62) de filtrage enroulé en spirale, le mécanisme de tension à courant continu pulsé étant électriquement connecté en parallèle au condensateur (62) de filtrage enroulé en spirale, et le condensateur (62) de filtrage enroulé en spirale étant électriquement connecté en parallèle au dispositif de précipitation électrostatique (66). On utilise éventuellement une résistance (65) pour abaisser la tension transitoire du condensateur (62) de filtrage enroulé en spirale. Un mécanisme de commutation peut être utilisé pour appliquer des niveaux variables de capacitance et d'inductance afin d'appliquer une gamme de formes d'onde de tension au dispositif de précipitation électrostatique (66) pour potentiellement accroître l'efficacité de collecte de particules du dispositif de précipitation électrostatique (66).
